I installed Windows 7 and forgot to do something about saving my Firefox settings except for a full backup through Windows Backup. I also copied all my files in my home directory to an external drive, not fully trusting Windows Backup to get everything I needed. So I essentially have 2 ways of getting back my old files.

Now I would like to get my profile from the previous installation to work in the freshly installed Windows 7 system. Can this be done if I have the previous files under AppData?

What do I do to restore the profile?

I also happen to have all of the old files in C:\Windows.old if I need them.

Btw, I did try copying the old profile files back in place (see location below) but it just did not work.
